init

Initialize; if you need the wicket servlet/filter for initialization, e.g. because you want
to read an initParameter from web.xml or you want to read a resource from the servlet's
context path, you can override this method and provide custom initialization. This method is
called right after this application class is constructed, and the wicket servlet/filter is
set. Use this method for any application setup instead of the constructor.
